Folders contain following files:

1. CAD: table step and stl files for NEMA17 and NEMA23 type stepper motors,
2. GERB: gerber files for production (upload to JLCPCB and have fun),
3. Kicad: Kicad 6 project files, so you can fiddle to your hert's content.

I have also uploaded a schematic in pdf file and sample code in micropython for Wemos D1 mini (ESP8266) and Wemos S2 (ESP32) boards in main folder. Tripple check GPIOs on your version of ESP before uploading the code!
